If you can't afford a ridiculously tricked-out shower, the next best thing might be a Smart Shower from Hansa. It has a standard shower, cascade and hand shower mode for your head, and a pivoting spray for your crotch.
Well it could be used for your crotch if you are tall enough, or you have a weirdly high crotch with a weirdly short torso. Either way, it's a sweet-looking fixture with a lot of options. [Hansa via Trendir]
